That kind of inspired one of my periodic quests to re-read stuff I read as a kid, like the Great Brain books or the spooky John Bellairs stuff or the Bruno and Boots books by Gordon Korman.
There are always a few books that I remember odd details from (using jelly beans as face paint; impersonating a boy in order to fight in the Revolutionary War) but can't put a title or author to . . . which is where "Stump the Bookseller" on the Loganberry Books Web site comes in. I found this site a while back, and I thought I had posted something here about it already, but apparently not.
I actually solved one — someone posted details that I recognized as part of Sister of the Bride, a Beverly Cleary book from 1963 that I just reread last summer. So, yay me?
